From 49b1f4b44bcdc47a10d2b354b269305043ef2a32 Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Wed, 23 Jul 2008 21:31:02 -0700 Subject: tridentfb: acceleration code improvements This patch brings various acceleration improvements: - set copyarea/fillrect for non-accelerated framebuffer (fix) - remove 15 bpp depth handling to simplify code as it hardly works (15 bpp handling was obviously missing in some switches) - add fb_sync call and move waiting before accelerated function to make acceleration more asynchronous to cpu (few % of speed improvement) - add cpu_relax() call in waiting loops - make longer register names and name more registers - move registers' definition to header - general code improvements (shortening, simplifying) Signed-off-by: Krzysztof Helt Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/video/trident.h | 21 ++++++++++++++++++++- 1 file changed, 20 insertions(+), 1 deletion(-) (limited to 'include/video') diff --git a/include/video/trident.h b/include/video/trident.h index 76d81b2..7540501 100644 --- a/include/video/trident.h +++ b/include/video/trident.h @@ -4,7 +4,7 @@ #endif #if TRIDENTFB_DEBUG -#define debug(f,a...) printk("%s:" f, __FUNCTION__ , ## a);mdelay(1000); +#define debug(f,a...) printk("%s:" f, __FUNCTION__ , ## a);mdelay(100); #else #define debug(f,a...) #endif @@ -124,3 +124,22 @@ #define BiosMode 0x5c #define BiosReg 0x5d +/* Graphics Engine */ +#define STATUS 0x2120 +#define OLDCMD 0x2124 +#define DRAWFL 0x2128 +#define OLDCLR 0x212C +#define OLDDST 0x2138 +#define OLDSRC 0x213C +#define OLDDIM 0x2140 +#define CMD 0x2144 +#define ROP 0x2148 +#define COLOR 0x2160 +#define SRC1 0x2100 +#define SRC2 0x2104 +#define DST1 0x2108 +#define DST2 0x210C + +#define ROP_S 0xCC +#define ROP_P 0xF0 +#define ROP_X 0x66 -- cgit v1.1
